Data from animal models have shown that hepatic graft-versus-host disease (GVHD) may be mediated by donor T cells interacting with liver adhesion molecules, other minor histocompatibility antigens, or both. We hypothesized that T-cell infiltrates within a liver biopsy during clinical GVHD would show a restricted T-cell response because the T cells would be responding to a limited number of antigens. We studied the peripheral T-cell repertoire and the liver-infiltrating T-cell repertoire of a patient who developed skin GVHD and subsequent liver GVHD after a matched sibling bone marrow transplantation for acute myeloid leukemia. Spectratype analysis of peripheral blood at the time of liver GVHD revealed that the patient had reconstituted a complex peripheral T-cell repertoire as evidenced by the presence of complementarity-determining region 3 (CDR3) length heterogeneity in most of the T-cell families. The repertoire complexity was skewed in variable gene beta (VB) 5.3, VB4, VB7, VB8, and VB15. Spectratype analysis on the liver biopsy sample revealed a limited infiltrate with an oligoclonal expansion in VBs 4, 7, and 8. We evaluated the T-cell infiltrate in more detail by sequencing the relevant expansions noted by spectratype and developing probes for the predominant CDR3 sequences. These clonotype probes were hybridized to peripheral blood and liver samples from the patient, a T-cell line developed from the patient's peripheral blood at the time of the initial skin GVHD, the donor's blood and marrow, and control samples. The results showed that the T-cell infiltrate during liver GVHD is mediated by a limited number of T cells, and that those cells are mostly different from the ones expanded from the peripheral blood during an acute skin GVHD reaction. These data support the concept that liver GVHD is a response to tissue-specific minor histocompatibility antigens.
